Abstract (en)
[origin: EP0417734A1] A refractory sheet member (4) is positioned in a cut-out portion (2) of graphite side and end plates (1,3) of an aluminum holding and refining vessel comprised of an externally heated cast iron tub to create an effective barrier to the flow of molten aluminum through the channel formed upon the pulling of the plates apart when the vessel is heated to operating temperature.
